DUAL PRECISION SERIES
PISTON PUMPS

With two pump heads on a single motor the Dual Precision Series offers the highest precision for synchronized dosing.

The Dual Precision Series’ innovative design allows precise mixing, simultaneous dosing or out-of-phase delivery. Combining pumps on a single motor saves space and reduces motor control requirements without sacrificing precision. Furthermore, relative dispense volumes never change because the pumps spin on the same shaft.

Using different size pump heads and using different calibrations allow mixing ratios as high as 160:1. Rinse port options are available when pumping fluids that form precipitates.

The speed and direction are detected by an optical sensor for feedback independent of the stepper motor.

Depending on size each pump head is capable of a displacement of 25 to 4000 µL / stroke.

MIXING

Ideal made for mixing ratios from 1:1 to 160:1. With two calibrated pumps connected to the same motor you’ll never have to worry about relative motor speeds.

CHEMICALLY RESISTANT

Our pumps are made from materials that are resistant to a wide range of aggressive chemicals. This means our pumps can also operate reliably and precisely in even the most severe environments.

ADJUSTABLE STROKE VOLUME

Our pumps are versatile. With angle adjustment, a piston-type pump can deliver various doses. This allows you to relieve one piston pump of larger volumes and create synergy.
